The defensive tackle is not ready to say that. The Vikings are still in the mix to re-sign the 11-year veteran even after agreeing to terms with defensive tackle Linval Joseph, who should complete Minnesota's starting defensive line.

"The Vikings have got to do what they've got to do," Williams said Wednesday about Tuesday's move on Joseph. "We'll know in a few days (where Williams will sign)."

If Williams, 33, were to return to Minnesota, it likely would be as a backup. He wouldn't say whether he would be willing to accept that role after being a starter his entire career.

"I'm just waiting, and in few days I'll make my decision," he said.

With end Jared Allen leaving in free agency and tackle Letroy Guion having been released, the Vikings are in line to have three new starters on the defensive line. The projected starters are Joseph and second-year man Sharrif Floyd at tackle, and holdover Brian Robison and Everson Griffen at end. Griffen signed a five-year, $42.5 contract this week after having been a Minnesota reserve.

Williams has been one of the better linemen in Vikings history. He's made six Pro Bowls and been named first-team all-pro five times.
